Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object existing in the vicinity without mechanical contact using the force of an electromagnetic field or infrared rays. As the proximity sensor 141 , the proximity sensor 141 may be disposed in an inner region of the vehicle display device covered by the above-described touch screen or near the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive type proximity sensor, a magnetic type proximity sensor, and an infrared proximity sensor. When the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of an object having conductivity by a change in an electric field according to the proximity of the object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, the act of approaching an object on the touch screen without contacting it so that the object is recognized that it is located on the touch screen is called “proximity touch”, and the touch The act of actually touching an object on the screen is called "contact touch". The position where the object is touched in proximity on the touch screen means a position where the object is perpendicular to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) have. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further, provides visual information corresponding to the processed data. It can be printed on the touch screen. Furthermore, the controller 180 may control the vehicle display apparatus 100 to process different operations or data (or information) according to whether a touch to the same point on the touch screen is a proximity touch or a contact touch. have.

The touch sensor detects a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. do.

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific part of the touch screen or a change in capacitance occurring in a specific part of the touch screen into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, an electrostatic capacitance at the time of touch, etc. in which a touch object applying a touch on the touch screen is touched on the touch sensor. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

As such, when there is a touch input to the touch sensor, a signal(s) corresponding thereto is sent to the touch controller. The touch controller processes the signal(s) and then transmits corresponding data to the controller 180 . Accordingly, the controller 180 can know which area of the display unit 151 has been touched, and the like. Here, the touch controller may be a component separate from the controller 180 , or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or may perform the same control according to the type of the touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of the touch object may be determined according to the current operating state of the vehicle display apparatus 100 or a running application program.

On the other hand, the above-described touch sensor and proximity sensor independently or in combination, a short (or tap) touch on the touch screen (short touch), long touch (long touch), multi touch (multi touch), drag touch (drag touch) ), flick touch, pinch-in touch, pinch-out touch, swype touch, hovering touch, etc. It can sense touch.

The ultrasonic sensor may recognize position information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the position of the wave source through information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source may be calculated using the property that light is much faster than ultrasonic waves, that is, the time at which light arrives at the optical sensor is much faster than the time at which ultrasonic waves reach the ultrasonic sensor. More specifically, the position of the wave source may be calculated using a time difference from the time that the ultrasonic wave arrives using light as a reference signal.

On the other hand, the camera 121 as seen in the configuration of the input unit 120 includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing target for a 3D stereoscopic image. The photo sensor may be stacked on the display device, and the photo sensor is configured to scan the motion of the sensing target close to the touch screen. More specifically, the photo sensor mounts photo diodes and transistors (TRs) in rows/columns and scans the contents placed on the photo sensors using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing target according to the amount of change in light, and through this, location information of the sensing target can be obtained.

The display unit 151 displays (outputs) information processed by the vehicle display apparatus 100 . For example, the display unit 151 may display information on an execution screen of an application program driven in the vehicle display device 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the information on the execution screen. have.

Also, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

Due to the above-described structure, the second frame 2200 and the second roller 2320 may be guided by the guide bar 2730 to move in the first direction. Since the guide bar 2730 is made of a solid material and one side is fixed to the first frame 2100 , it is possible to stably support movement of the second frame 2200 and the second roller 2320 in the first direction.

In the embodiment, since the first direction movement of the second frame 2200 and the second roller 2320 is stably supported by the guide bar 2730, the second frame 2200 and the second roller 2320 are unstable. As a result, it is possible to effectively suppress wrinkling or damage of the flexible display 2400 caused by moving in the first direction, damage or malfunction of the vehicle display device, and the like.

The moving unit 2500 may further include a first magnet 2540 . The first magnet 2540 may be disposed on a part of the flexible display 2400 to couple the flexible display 2400 to the backplate 2530 .

As shown in FIG. 11 , a plurality of first magnets 2540 may be provided, and each of the first magnets 2540 may be arranged in an appropriate number horizontally and vertically on a portion of the flexible display 2400 . In this case, it is appropriate to select a portion where the flexible display 2400 is not bent by the second roller 2320 among the flexible displays 2400 provided with the first magnet 2540 .

The first magnet 2540 may be, for example, attached to the rear surface of the flexible display 2400 , that is, a surface facing the back plate 2530 , by an adhesive.

In the embodiment, the flexible display 2400 and the backplate 2530 are rigidly coupled to each other by the first magnet 2540 , so that the backplate 2530 is the flexible display 2400 due to repeated movement of the flexible display 2400 . ) can be effectively suppressed.

In the display apparatus for a vehicle, the size change of the external exposure area of the flexible display 2400 may be manually performed by a driver or the like. For example, when the driver pushes up the front surface of the flexible display 2400 , the first roller 2310 may rise to increase the external exposure area of the flexible display 2400 . Conversely, when the driver pushes down the front surface of the flexible display 2400 , the first roller 2310 may descend to reduce an external exposure area of the flexible display 2400 .

In order to smoothly operate the display device for a vehicle, it is necessary to appropriately adjust the magnitude of the restoring force of the second elastic part 2720 .

In another embodiment, the vehicle display apparatus may include an actuator 2650 that automatically changes the size of the external exposure area of the flexible display 2400 . 11 and 12 , the vehicle display apparatus may further include an actuator 2650 that operates the guide unit 2600 . The actuator 2650 may include a rack gear 2651 , a pinion gear 2652 , and a motor 2653 .

The rack gear 2651 may be formed on the movable plate 2510 and disposed in a longitudinal direction parallel to the first direction. The pinion gear 2652 may be disposed to mesh with the rack gear 2651 . At this time, in order to maintain the state in which the pinion gear meshes with the rack gear 2651 , a casing for bringing the pinion gear 2652 and the rack gear 2651 into close contact with each other may be provided.

The motor 2653 may be provided to rotate the pinion gear 2652 . The motor 2653 may be fixed to the dashboard 10 of the vehicle or an empty space of the vehicle display device.

As the pinion gear 2652 is disposed on the rotation shaft of the motor 2653 , the pinion gear 2652 rotates by the rotation of the motor 2653 , and the rack gear 2651 meshing with the pinion gear 2652 moves in the first direction. , and thus the movable plate 2510 on which the rack gear 2651 is formed may move in the first direction.

As the pinion gear 2652 rotates, the moving plate 2510 moves in the first direction, and the first control bar 2620 and the second control bar 2630 are connected to each other around the coupling portion. can rotate

That is, as the moving plate 2510 moves in the first direction, the second frame 2200 and the second roller 2320 move in the first direction, and thus the external exposure area of the flexible display 2400 increases or can decrease.

The control unit 180 provided in the vehicle display device is electrically connected to the motor 2653 to control the operation of the motor 2653, so that the increase or decrease of the external exposure area of the flexible display 2400 is transmitted to the control unit 180. can be controlled by

The second magnet 2900 may be provided to be fixed to the second frame 2200 . Accordingly, the hall sensor 2800 is fixed, and the second magnet 2900 may move together with the second frame 2200 in the first direction. The Hall sensor 2800 may be connected to the controller 180 .

When the hall sensor 2800 senses the separation distance from the second magnet 2900 , the controller 180 provided in the vehicle display apparatus may determine the external exposure area of the flexible display 2400 .

That is, the Hall sensor 2800 detects a change in the magnetic field by the second magnet 2900 as the second magnet 2900 moves in the first direction, and based on this, the controller 180 controls the Hall sensor 2800. A distance in the first direction between the and the second magnet 2900 may be determined. The controller 180 may determine the external exposure area of the flexible display 2400 based on the distance in the first direction between the hall sensor 2800 and the second magnet 2900 .

14 is a perspective view illustrating a chain 2520 according to an embodiment. 15 is a diagram for explaining the operation of the chain 2520 according to an embodiment.

As described above, the chain 2520 is provided to replace the support bar 2550 , and may play the same role as the support bar 2550 . Accordingly, one end of the chain 2520 may be coupled to the movable plate 2510 , bent by the first roller 2310 , and provided to support at least a portion of the rear surface of the flexible display 2400 .

The chain 2520 may be made of, for example, metal, and one end of the chain 2520 moves with the chain 2520, for example, so that a pin is formed and the pin is embedded in the moving plate 2510. The plates 2510 may be coupled to each other. However, the coupling method is not limited thereto.

Since the structure of the support bar 2550 has been described above, overlapping descriptions of the chain 2520 and the support bar 2550 will be omitted, and a specific structure of the chain 2520 will be described below.

The chain 2520 may include a first link 2521 , a second link 2522 , and a link pin 2523 . Each of the first link 2521 and the second link 2522 is formed in plurality.

The plurality of first links 2521 are arranged along the front-rear direction, the plurality of second links 2522 are also arranged along the front-rear direction, and the first link 2521 is coupled to the second link 2522 with each other.

For fastening of the first link 2521 and the second link 2522 , a first link hole 2521a is formed in the first link 2521 , and a second link hole 2522a is formed in the second link 2522 . is formed, and the link pin 2523 is inserted and coupled to the first link hole 2521a and the second link hole 2522a.

The first link 2521 and the second link 2522 may be relatively rotated using the link pin 2523 coupled thereto as a rotation axis. Two identical first link holes 2521a may be formed to be spaced apart from each other in the first link 2521 , and two identical second link holes 2522a may be formed to be spaced apart from each other in the second link 2522 .

The link pin 2523 may have a circular cross-section, and the second link hole 2522a may also have a circular cross-section. The first link hole 2521a has a diameter in the longitudinal direction of the chain 2520 . It may be formed in the form of a long slot hole. That is, the first link hole 2521a has a larger diameter (d2) in the longitudinal direction (larger by α) than the diameter (d1) in the thickness direction.

For example, the first link hole 2521a may have a diameter d2 in the longitudinal direction greater than the diameter d1 in the thickness direction by 0.2 mm.

Unlike when the chain 2520 (a combination of links) is in a straight shape, when the chain 2520 is bent, for example, when the chain 2520 is bent around the first roller 2310, the chain 2520 ), the spacing between some links should be widened from each other, or the spacing between some links should be close to each other. This is because the chain 2520 wound around the first roller 2310 cannot form a part of a perfect circle (eg, a complete semicircle).

In the display device for a vehicle according to the embodiment, in consideration of this point, the first link hole 2521a is made in the form of a long hole having a long diameter in the longitudinal direction of the chain 2520 , and accordingly, the length of the chain 2520 is compensated. making this happen.

The vehicle display apparatus according to the embodiment may further include a third frame 2003 . Referring to FIG. 15 , the third frame 2003 may be fixedly coupled to the lower end of the inner plate 2640 , and the first roller 2310 may be rotatably coupled to the third frame 2003 .

For example, the third frame 2003 is provided as a pair, and each third frame 2003 is fixedly coupled to both sides of the lower end of the inner plate 2640, and thus, each third frame 2003 Both ends of the first roller 2310 may be rotatably coupled thereto.

By the third frame 2003, the first roller 2310 is rotatably coupled to the inner plate 2640 which does not move in the first direction, and thus, the chain 2520 is formed by the first roller 2310. While being stably supported, it can be bent by the first roller 2310 and move in the first direction at the same time.

The structure of the third frame 2003 may also be employed in a vehicle display device provided with the support bar 2550 .

Meanwhile, instead of the third frame 2003 , the first roller 2310 may be supported by using the first elastic part 2710 . 16 is a view for explaining the operation of the first elastic part 2710 according to an embodiment. 17 is a perspective view illustrating a first elastic part 2710 according to an exemplary embodiment.

The vehicle display device may include a first elastic part 2710 instead of the third frame 2003, wherein the first elastic part 2710 is mounted on the inner plate 2640 and the inner plate 2640 and The first roller 2310 may be disposed at a portion facing each other, and the second roller 2320 may be elastically supported.

The first elastic part 2710 may include an elastic body 2711 and a pusher 2712 . The pusher 2712 may be formed with a protrusion for mounting the elastic body 2711 . Referring to FIG. 16 , a hole into which the protrusions of the elastic body 2711 and the pusher 2712 are inserted may be formed at the lower end of the inner plate 2640 .

The elastic body 2711 may be formed, for example, in the form of a coil spring. The elastic body 2711 may store elastic force in a compression-deformed state, and may be configured to press the first roller 2310 in this state.

The elastic body 2711 may be provided to press the first roller 2310 via the pusher 2712 . In another embodiment, without using the pusher 2712 , only the elastic body 2711 may be mounted on the lower end of the inner plate 2640 to press the first roller 2310 .

By the first elastic part 2710 , the first roller 2310 may be pressed to be in close contact with the chain 2520 , and thus the chain 2520 is stably supported by the first roller 2310 while being stably supported by the first roller 2310 . It is bent by 2310 and can move in the first direction at the same time.

The structure of the first elastic part 2710 may also be employed in a vehicle display device in which the support bar 2550 is provided.

The guide part 2600 may further include a second elastic part 2720 . 18 is a view for explaining the operation of the second elastic part 2720 according to an embodiment.

A second elastic part 2720 is disposed at a coupling portion between the first control bar 2620 and the second control bar 2630 , and is formed between the first control bar 2620 and the second control bar 2630 . Rotation can be supported elastically.

The second elastic part 2720 may be provided as, for example, a torsion spring. The second elastic part 2720 may be mounted through a coupling portion in which the first control bar 2620 and the second control bar 2630 rotate with each other, and one end of the first control bar 2620 and the other end of the second control bar 2620 are second. 2 It may be fixedly coupled to the control bar (2630).

The second elastic part 2720 applies a rotational force to the first control bar 2620 and the second control bar 2630 in a direction in which the angle between the first control bar 2620 and the second control bar 2630 increases. It can be provided to apply.

Due to this structure, when a driver or the like manually manipulates the vehicle display device to increase the external exposure area of the flexible display 2400, the force required for the first roller 2310 to smoothly rise in the first direction is applied to the vehicle. It may be provided to a display device.

19 is a view showing a back plate 2530 according to an embodiment. The back plate 2530 may be formed of a metal plate having elasticity. For example, the back plate 2530 may include a superelastic metal.

The back plate 2530 facilitates elastic deformation and elastic recovery of the flexible display 2400 .

The back plate 2530 may be formed in a relatively thin plate shape. For example, the back plate 2530 may be formed to have an arbitrary thickness in the range of 0.05 to 0.2 mm, and may be formed to have a thickness of 0.1 mm.

The back plate 2530 is made of an integral metal plate as a whole and may be divided into two or more regions. Specifically, the back plate 2530 may include a fixed region 2530a and a deformable region 2530b.

The fixed area 2530a is an area overlapping a non-bending portion of the flexible display 2400 . In the fixed area 2530a, the back plate 2530 may be formed in the form of a flat metal plate as a whole.

In the back plate 2530 , a through hole 2535 may be formed in a portion corresponding to the roller, that is, the deformation region 2530b. The deformable area 2530b is an area overlapping the bent portion of the flexible display 2400 . Through-holes 2535 which are a plurality of through-holes long in the width direction (left and right directions) are formed in the deformation region 2530b. That is, a plurality of through-holes passing through the thickness direction of the back plate 2530 in the deformation region 2530b are formed.

In the deformable region 2530b, the back plate 2530 may be symmetrical. The deformable region 2530b in which the plurality of through-holes 2535 are formed may include a corner portion 2531 , a horizontal connection portion 2532 , and a first vertical connection portion 2533 .

The corner portions 2531 are divided into a plurality to form left and right corners of the back plate 2530 . The corner portions 2531 have a predetermined length along the longitudinal direction, and each corner portion 2531 is spaced apart from each other.

The horizontal connection part 2532 extends in the width direction from the corner part 2531 , and two horizontal connection parts 2532 extend from one edge part 2531 .

The first vertical connection portion connects two horizontal connection portions 2532 extending from different corner portions 2531 to each other. That is, the first vertical connection portion 2533 extends from the two adjacent corner portions 2531 , and connects the two horizontal connection portions 2532 adjacent to each other. The first vertical connection parts 2533 may be repeatedly formed along the width direction (left and right direction), and each of the first vertical connection parts 2533 may be spaced apart from each other at equal intervals.

A second vertical connection portion 2534 may be formed in the deformation region 2530b, and the second vertical connection portion 2534 connects two horizontal connection portions 2532 extending from the same corner portion 2531 to each other. The second vertical connection portions 2534 may be repeatedly formed along the width direction (left and right directions), and each of the second vertical connection portions 2534 may be spaced apart from each other at equal intervals.

As described above, in the deformable region 2530b, the long through-holes 2535 in the width direction are repeatedly formed, so that the deformable region 2530b can be easily bent about the rotation axis in the width direction.

And when a tensile force, which is an external force, is applied along the longitudinal direction in the deformation region 2530b, the corner part 2531 and the first vertical connection part 2533 about the horizontal connection part 2532 may be deformed in a direction away from each other in the longitudinal direction. In addition, the length may be increased over the entire area of the deformable area 2530b. When the external force is removed, the deformable region 2530b may be restored to its original state while being elastically restored.

Also, when a tensile force, which is an external force, is applied in the deformation region 2530b in the longitudinal direction, the first vertical connection part 2533 and the second vertical connection part 2534 are deformed in a direction away from each other in the longitudinal direction around the horizontal connection part 2532 . In this case, the length may be increased over the entire area of the deformable area 2530b. When the external force is removed, the deformable region 2530b may be restored to its original state while being elastically restored.

Since the deformable region 2530b is provided in the backplate 2530 , the bent region of the flexible display 2400 may be more flexibly deformed. When the flexible display 2400 is bent in a portion adjacent to the second roller 2320, elastic deformation of the flexible display 2400 is easy, and the flexible display 2400 can be easily controlled in springback.

In addition, since the deformable region 2530b is provided in the back plate 2530 , the flexible display 2400 may be elastically deformed within a predetermined range along the longitudinal direction.

In the embodiment, the size of the displayed screen may be adjusted according to the user's convenience by manually adjusting the external exposure area of the flexible display 2400 by the user or automatically by the actuator 2650 .

Meanwhile, the controller 180 provided in the vehicle display apparatus may control the driving of the vehicle display apparatus to have an external exposure area set based on the characteristics of each user or each apparatus provided in the vehicle.

For example, the controller 180 may control the external exposure area of the vehicle display device based on the user's input value. That is, the user inputs a numerical value for the external exposure area of the vehicle display device into the input unit 120 , and the controller 180 controls the external exposure area of the vehicle display device according to the input value. You can conveniently view the displayed image or information from

Also, for example, the flexible display 2400 reproduces a screen for controlling a device provided in the vehicle, and the controller 180 controls the external exposure area to be different according to the characteristics of each device provided in the vehicle. can

Specifically, the flexible display 2400 may reproduce a navigation screen, a screen for operating the air conditioner, and a screen for controlling a driving device on which a brake, a speedometer, and the like are displayed. At this time, in order for a user such as a driver to conveniently and accurately recognize the destination and the current vehicle location, when the navigation screen is reproduced, the external exposure area of the flexible display 2400 is larger than in other cases. The vehicle display device may be controlled to be larger.

Also, for example, the controller 180 identifies each user by recognizing the face of a user in the driver's seat from a camera provided in the vehicle display device, and based on a value set according to each identified user, the flexible display The size of the external exposure area of 2400 may be controlled.
